ALBERT N. NORRIS, OF RUSHVILLE, INDIANA.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 276,869, dated May 1, 1883.

Application filed November 3, 1882. (No model.)

To all whom itmay concern:

Be it known that I, ALBERT N. NORRIS, a resident of Rushville, in the county of Bush and State of Indiana, have invented a new and useful Improvement in Corn-Planters, of which the following is a specification, having reference to the accompanying drawings.

My invention relates to that class of cornplanters in which the amount of seed delivered is regulated by a bevel-wheel attached to the feed-plate and provided with two or more concentric rows of cogs, and a pinion on the driving-shaft adapted to slide thereon and to intermesh with either row of cogs on the first-mentioned wheel.

In this class of corn-planters as heretofore constructed the means for throwing the pinion out of gear with the bevel-wheel attached to the feed-plate and the means for moving said pinion-from one row of cogs to another on the bevel-wheel have been separate devices.

The object of my invention is to provide a more convenient means for changing the pinion from one row of cogs to another on the feed-wheel 5 and it consists, first, in mounting the pinion in abearing having a combined swinging and sliding motion, as hereinafter fullydescribed.

My invention consists, further, in the combination, with the above-mentioned pinion and its swinging sliding bearing, of a lever, a swinging fulcrum therefor,a notched segmentbar, and means for securing the lever in the notches of the segment-bar, wherebythe pinion is moved and controlled, as hereinafter fully set forth.

The accompanying drawings illustrate my invention, in which Figure l is a side elevation of my invention, the seed-box, feed-plate, and shaft and its bevel-gear being shown in section. Fig. 2 is a rear elevation of the same.

Like letters refer to the same parts in both figures.

a represents the rear end of the cornplanter frame; b, the seed-box, and c the feedplate. Secured tothe feed-plate shaft is a bevel-wheel, e, having three concentric rows of teeth.

f is a pinion having teeth adapted to intermesh with either row of teeth on wheel 0, and

and partially revolve g has a central longitudinal square hole, in

which the squared end of the driving-shaft t loosely fits. Shaft i is supported at its other end by a suitable socket-bearin g, and is caused to revolve by a pair of bevel-wheels connecting it with the carrying-wheel in the usual well-known manner. Arm h is fastened to or formed upon a rod, j, which is adapted to sllde in a bearing, k, secured to the frame a.

7 To the rear end of rod j is pivoted one end of a lever, l, which has its fulcrum at m on the swinging standard it, the lower end of standard at being pivoted in bearings 0 0, secured to the frame. Lever l is provided with a projecting rib, 1), Fig. 2, whichisadapted to engage either one of ase'ries of notches, t, in a bracket or segment-bar, 1",secured to the frame. Lever l is held in place against bar 1 by means of a thumb-latch, S, pivoted to one side of the lever in such manner as to embrace the bar.

The operation of my device is as follows: The operator, desiring to change the amount of corn dropped during onerevolution of the carryin g-wheel, seizes lever l and disengages it from the segment-bar, and by pressing his thumb on latch s swings the lever away from the bar, thus withdrawing rib p from the notch. t and partially revolving rodj and arm h, thereby dropping pinion f out of contact with bevelwlfeel 6. By pressing the lever backward or forward, rod j and carrying-arm h are slid correspondingly till pinion fis brought opposite another row of teeth on wheel 6, with which it is engaged by swinging the lever back against the segment-bar and dropping latch s, rib p engaging another notch and preventing the slipping of the pinion backward or for- 2 menses segment-bar, and means for securing the le- 10 ver in the notches of the segment-bar, all substantially as shown and described,for the purpose specified.

ALBERT Nfnonnis.
